To all whom it may concern:

- Be \it known that I, Oren, F. ADAMSOIQZ Specification of Letters Patent. Application filed 0ctober 2 5, 1911.

citizen of the United States, residing at Aki ron, in the county of Summit and State of Ohio, have invented certain new and useful vices for Tires, of which the following is a specification.

The present invention relates in general to devices for vulcanizing rubber, and more particularly to that type of vulcanizing de- Improvements in PortableVulcanizing De'-' vices which are adapted to be employed for the repairing of tires or the like.

Among the objects of the invention is 'to' provide a vulcanizing device which is simple and inexpensive in its construction,

which is light and compact in its design andcan bereadily carried from place to place, ..which can be easily and quickly appl ed to 20 the member to be vulcanized, and which will operate in a quick and eflective manner to vulcanize the rubber to which it is applied.

A further object of the invention is to provide a vulcanizing device which embodies novel features of construction whereby the use of a steamor water: jacket is eliminated and the vulcanizing member is heated directly from the flame, the temperature of the vulcanizing member being automatically controlled without the use of any special or complicated mechanism. a

With these and other objectsin view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims/ For a full understanding ofthe invention, reference is to be had to the following description and accompanying drawings, in

which ing device constructed in accordance-with the invention. Fig. 2 is a longitudinal ver- Itical sectional view through the same on the line 2-2 of Fig. 1, and Fig.3 is a top plan view showing a modified-construction of the vulcanizing device. Qorresponding and like parts are referred tojin the following description and indicated in all the views of the drawing by the same reference characters.

Specifically describing the embodiment of the invention illustrated by Figs. 1 and 2 of the drawing, the numeral 1 designates a vulroaranm vurcamzme DEVICE m TIRES.

. canizing plate which-maybe of any desired shape and size and is designed to have one face thereof applied to the material to be vulcanized. In the present instance the lower surface of the plate constitutes the vulcanizing surface and is slightly concaved, as indicated at 1 An annular or continuous flange 2 projects upwardly from the plate l-soas to form a receptacle adapted to receivesome combustible fluid such as gasolene or alcohol. Any suitable means may be employed for holding the vulcanizing plate against the material to be vulcanized, and in the present instance this result is accomplished by means of a clamping plate 3 which cooperates with the vulcanizing plate or member to grip the material to be vulcanized. The clamping plate 3 is illustrated as provided at opposite sides thereof with ears 4 which carry clamping screws 5, the

said clamping screws being adapted. to be engaged by hooked ears 6, which project from opposite sides of the vulcanizing mem-. her or plate 1. Thumb nuts 7 are applied to the clainping-screws-5 and constitute a means for drawing the clamping plate against the vulcanizing member so as to firmly grip a rubber tire or like object placed between the same.

In order to heat the vulcanizing member or plate 1, a suitable quantity of some combustible liquid is placed in the receptacle, as indicated at 8 in Fig. 2, and the surface of the combustible fluid ignited. It has been foundthat the desired temperature at which the vulcanizing member l-should be retained in order to effectively vulcanize the rubber is substantially the same as the boiling point of the gasolene or like combustible fluid which is placed in the receptacle. The com- E bustible fluid 8 rests upon the vulcanizing F igure 1 1s a top plan view of a vulcamzplate and is in direct contact therewith at a point opposite the vulcanizing surface, so that the combustible fluid and vulcanizing plate are simultaneously heated and It will also be observed that the combustible fluid is interposed between the flame or combustion and the vulcanizing plate so as to form a protecting agent and prevent the vulcanizing plate from being overheated by the flame.

It has been found desirable to provide some means for conducting the heat from the flame above the combustible fluid down have approximately the same temperature.

' into the combustible fluid and vulcanizing patch to the inner tube ofa pneumatic tlre,

canizing member or quantity of 2 be placed in the receptacle and ignited. The

a 'piece of suitably prepared rubber 10 would be applied to the defective portion of the tube 11 and the said members clamped between the clamping plate 3 and the vulplate 1. A suitable combustible fluid 8 would then flame caused by the combustion of the gases rising from the combustible fluid would act directly upon theposts 9 and heat would be conducted by; the posts down into the combustible fluid and the vulcanizing plate. As the temperature of the vulcanizing plate and combustible fluid rises, the 'rapldity with which the gas is given off from the surface ofthe combustible fluid. increases so that the zone of'combustion rises within. the receptacle. This rising of the flame is due to the fact that the rapid generation of the gas prevents the air from mixing produce combustion until after the gas has risen to a greaterheight abovethe surface of the fluidthan would be necessary where the fluid was at a lower temperature and the generation 0f gas less rapid. When the temperature of the yulcanizin plate reaches the maximum point which 1s desired for vulcanizin purposes, the generation of gas at'the sur ace of the combustible fluid will have become so rapid as to force the flame entirely up to the top of the flange 2 and the posts 9. The flame then becomes ineffective for the-purpose of heatingthe osts or receptacle,and the temperature 0 the vulcanizing plate and combustible fluid will gradually lower until the flameagain drops within the receptacle and becomes eflTect-ive. The height of the flame above the'surface of the fluid and the cdnsequent effectiveness of the flame as a{h ating agent is 'thusregu lated by the tembprpfture oi?- the combustible fluid so as to autrfinatically control the temperature of the vulcaniz'ingmember or plate '1 and prevent the z's'ame' from becoming either over or under heat-ed during the vulcanlzmg'operation. This operation will con- 4 tinue until the combustible fluid 8 has been entirely consumed, and it has been found that the vulcanizing effect will continue for a short period after the flame has extinguished, owing to theheat which is retained I ing a vulcanizin by the vulcanizing member. tion of the proper time required for vulcanization the vulcanizing member 1 s removed, the process being completed. It 15 also possible to place a redetermined quantity of the combustible At the expirauid within the receptacle so that the vulcanization of the rubber Wlll then have been completed by the time they fluid has been consumed,- at which time the vulcanizing member would be removed from the tire.

A slight modification is shown in Fig. 3

which a series of segmental ribs 12 arranged in concentric annular series are substituted for the posts 9 previously describeril.

The'eflect of the flame upon these ribs 12 is identical with that previously described in connection with the posts 9, it being merely desirable to provide some heat conducting mediums for conveyingthe heat from the zone of combustion above the combustible fluid down into both the combustible fluid and the'vulcanizing member.
